Patent DE-3016322-A1 (DE)
Title: Granular fuel feed for burner - uses pneumatic transport over part of feed with transport air also supporting combustion
Inventor: UNGER GUENTHER
IPC: F23K3/14
Filed: 1980-04-28
Abstract: The procedure for feeding lumpy or granular fuel to a burner involves pneumatic transportation at least part way. The fuel is pref. lump coal with an admixture of combustible refuse in lump or granular form. The conveyor-air may serve at least partially as combustion-air, any excess being either recirculated or admixed to the fluegas. Proportioning into combustion- and excess-air may be automatic, based on either fuel input quantity or combustion chamber temp. Some combustion-air may be used to cool the non-pneumatic part of the fuel feed system.

Title: Doppler radio direction finder - evaluates transient HF signals using circular array of cyclically scanned dipole antenna
Inventor: SCHMENGLER ECKHARD DIPL ING DR
IPC: G01S3/54
Filed: 1980-05-02
Abstract: A Doppler radio direction finder has several receiver antenna arranged on a circle and with a cyclic scanner. It can receive and evaluate horizontally polarised and abruptly occurring spatial waves of any polarisation in the short wave region, unlike devices with exclusively vertical monopoles or dipoles. This is aachieved without loss of directional sensitivity. Suitable frame or dipole antenna are used for reception of circularly polarised waves. They may be vertical crossed frame antenna or horizontally crossed dipole antenna. Individual frame or dipole antenna are scanned individually by the cyclic scanner. The individually acquired rotating receiver signals are assembled, using 90 degree phase shifts, into a left or right rotating circularly polarised signal by a further circuit. The left or right rotating output may be selected for evaluation by a switch.

Title: Vitamin-enrichment of flour - by wetting grain, keeping at room temp. and steaming at constant temp. before grinding
Inventor: BATSCHEIDER ALFRED
IPC: A21D2/38
Filed: 1980-06-25
Abstract: In natural vitamin-enrichment of flour, cereal grains are wetted to moisture content 16-20%, left to stand 3-6 hrs. at 12-23 deg.C and then kept 2-6 hrs. under steam at 60-70 (68) deg.C. The grains are advantageously washed before treatment, to prevent harmful material transport from surface to endosperm. Before steam-treatment, the grains are pref. re-dried to 12-14% moisture. After steam-treatment, the grains are cooled to room temp. and re-dried to grinding moisture 15-16%. Vitamins and minerals are transported, before grinding, from surface layer to endosperm. The vitamin content of finely-ground flour can be almost comparable to that of whole-wheat flour. Vitamin B1 enrichment can be 20% for 78% flour prodn. and 60% for 83% flour.

Title: Composite window section assembly device - locks together aluminium section and thermal barrier section using travelling bevelled rollers
Inventor: KELLER EBERHARD
IPC: E06B3/273
Filed: 1980-07-07
Abstract: The composite window section (1) consists of frame parts (2,3) fitted at a distance from each other. The two frame parts are made of aluminium and are kept apart by the plastics heat barrier (7). The two parts are placed next to each other on a supporting surface (11) and the box-shaped heat barrier section (7) is slid-in so that the raised edges (13) engage with the grooves formed by the protrusions (6) of the sections (4,5). The parts are clamped together by jaws (12) and in this condition a pair of bevel rollers (14), rotatingly seated on a ram (15) and vertically loaded by a pressure element (17), are made to travel along the protrusions (6) on the top part of the aluminium sections. The rollers (14) deform the protrusions (6) downwards producing a complete locking fit between the raised edges (13) and the protrusions (6).

Title: Motor vehicle heater using battery power only for starting - has combustion chamber and fan-driven heat exchange system
Inventor: POEDOER BALAZS
IPC: B60H1/22
Filed: 1980-08-19
Abstract: The vehicle heating unit is formed as a cylindrical tube into one end of which air is drawn after first passing through a filter. This fresh air passes between the inner wall of the outer cylinder and the outer wall of an internal cylinder. The inner cylinder is heated, and thus the air passing over it is also heated and leaves the opposite end of the heater as warm air. The inner cylinder is heated by a combustion chamber where fuel and air drawn in by a second fan are burnt together. The hot exhaust gases pass over the inner wall of the cylinder before they leave from an exhaust exit. The two fans are mounted on a common shaft which can be driven by an electric motor, the gas turbine forming an efficient and compact unit.

Patent DE-3108033-A1 (DE)
Title: Control valve for sprayers mounted on agricultural vehicles for treating the soil
Inventor: SCHMIERER HEINZ DIPL ING
IPC: A01M7/00
Filed: 1981-03-03
Abstract: A description is given of a control valve for sprayers mounted on agricultural vehicles for treating the soil. The said valve is arranged in a conduit coming from a tank and leading to a spray bar and is provided with a swivelling spindle for the adjustment of the valve element. The control valve is provided with an electric motor which can be reversed in its direction of rotation and is coupled coaxially to the swivelling spindle, the housing of the electric motor being provided on the valve side with a flange extending coaxially to the shaft of the electric motor, being held rotatably by means of the said flange on a base of the valve housing and can be locked on the latter. The advantage of such a control valve is to be regarded as the fact that it can be controlled both by hand and electrically from the cab of a tractor or the like. By virtue of the design according to the invention, the housing of the electric motor simultaneously serves as a handle for the mechanical actuation of the valve element. The control valve is designed in such a way that actuation of a locking pin by means of which the electric motor is fixed relative to the valve housing whilst in operation simultaneously breaks the circuit of the electric motor, so that the motor is always de-energised while being turned mechanically.

Title: Roof of a flat-roofed building
Inventor: MEHLHOSE DIETRICH
IPC: E04D13/15
Filed: 1981-03-06
Abstract: The invention relates to a roof of a flat-roofed building having a concrete ceiling (10) which rests on the masonry structure (11) of the building and, in the region of the roof edge, is surrounded by boarding elements (12a, 12b) designed as termination profiles. In the case of said roof, there is assigned to each boarding element (12a, 12b) a foamed plastic part in which there are arranged a retaining strip (35), running in the direction of the roof edge, and a plurality of parallel, vertical metal retaining sheets (34, 50) which are fastened at intervals on the retaining strip (35). As a result, the mounting operations can be reduced when producing the roof since the boarding elements (12a, 12b) are used as structural parts which can be largely prefabricated and assembled in a simple manner at the factory and can be easily mounted on the building site. <IMAGE>
